BACKGROUND The Pro12Ala polymorphism of the peroxisome proliferator-activated receptor-gamma2 (PPARgamma-2) gene has been variably associated with insulin resistance, obesity and type 2 diabetes in several populations. However, this association has not been studied in Iranian subjects and we hypothesized that this variation might be associated with insulin(More)
Sea cucumbers produce numerous compounds with a wide range of chemical structural diversity. Among these, saponins are the most diverse and include sulfated, non-sulfated, acetylated and methylated congeners with different aglycone and sugar moieties. In this study, MALDI and ESI tandem mass spectrometry, in the positive ion mode, were used to elucidate the(More)
Sea cucumbers, sometimes referred to as marine ginseng, produce numerous compounds with diverse functions and are potential sources of active ingredients for agricultural, nutraceutical, pharmaceutical and cosmeceutical products. We examined the viscera of an Australian sea cucumber Holothuria lessoni Massin et al. 2009, for novel bioactive compounds, with(More)
Sea cucumbers are prolific producers of a wide range of bioactive compounds. This study aimed to purify and characterize one class of compound, the saponins, from the viscera of the Australian sea cucumber Holothuria lessoni. The saponins were obtained by ethanolic extraction of the viscera and enriched by a liquid-liquid partition process and adsorption(More)

Sea cucumbers have been valued for many centuries as a tonic and functional food, dietary delicacies and important ingredients of traditional medicine in many Asian countries. An assortment of bioactive compounds has been described in sea cucumbers. The most important and abundant secondary metabolites from sea cucumbers are triterpene glycosides(More)
With attention to quality variations in commercial Dicalcium phosphates (DCPs) and their P bioavailability, aim of this study was to comparison of DCPs purchase from different Iranian factories in broiler grow performance. 256 male chickens (28-day old) were randomly selected for this experiment. 8 chickens with approximately same weight were placed in per(More)
Application of molecular technologies led to the discovery of mutations with major effects on the reproductive and meat efficiency of sheep and goat. This study aimed to identify mutations in exon 1 region of GDF-9 gene associated with twining was conducted using PCR-RFLP method on Sheep Hisari Tajikistan race. To identify polymorphisms in these loci(More)
